My 8 month old sits up straight in his chicco bouncer, and hands over the side to touch the floor. So I'm thinking he's too big for it now, not safe to leave him, (I thought that it would last longer than that?) but he can't sit unsupported yet. He has a jumperoo for limited play, and his high chair for meals that gets put away as not enough room in our flat. What else can I put him in of I need to do something? Thanks guys
